Abstract: 302,365. Koppers Co., (Assignees of Ackeren, J. van). Dec. 15, 1927, [Convention date]. Coke ovens.-In a coke oven battery the transversely-arranged regenerators 6 are connected to the heating-walls by horizontal conduits 15 running lengthwise of the battery, each conduit communicating with a number of regenerators and with certain of the flues in the corresponding heating-walls. In the battery of six ovens shown the vertical flues 13 are so grouped that, except for the end pairs of flues, four upflow flues alternate with four downflow flues along the whole length of the heating-wall. The regenerator chambers extend half the width of the battery and each can be put into communication with the atmosphere. with a gas main 8, or a waste gas flue 11. The conduits 15 correspond in number with the heating-flues in a wall, and each communicates with a pair of flues in each heating- wall, and each flue is in communication with a pair of conduits. Each regenerator chamber is connected to three of the twelve regenerator chambers. The air, gas, and waste gas connections are so made that an air regenerator is interposed between gas and waste gas regenerators, and a conduit 15 carrying air is similarly situated between conduits carrying gas and waste gas. Expansion of the structure is allowed for by the provision of joints 22 in the brickwork containing the conduits 15. Rich gas supplied through pipes 20 may be used for firing instead of lean gas preheated in the regenerators.

Abstract: 870,785. Treating waste materials. DANO INGENIORFORRETNING OG MASKINFABRIK INGENIOR KAI PETERSEN'S FOND. Oct. 30, 1959 [Nov. 1, 1958], No. 36996/59. Class 111. Apparatus for the fermentation of solid organic waste materials comprises a horizontally disposed rotatable container having distributed along its length apertures or groups thereof each connected with separate supply means for aeration medium under pressure. As shown, waste materials are fed into the container 1 from its left-hand end, as indicated with an arrow A in Fig. 1. The container 1 rotates in the direction of an arrow B (see Fig. 4) and the contents C will then occupy substantially the position indicated in Fig 4. By means of the distribution box 4, aeration medium (preferably air) supplied by the blower 6 will be forced only through the apertures which are in a lower portion of the container, so that the aeration medium supplied will be compelled to pass through the contents of the container. The screen plate 8, Fig. 3, constitutes a closing device which cuts off the supply of aeration medium to the pipes leading to an uppermost portion of the container, so that during the rotation of the container aeration medium is only supplied to those pipes 3 which extend over a lowermost portion of the container. As each of the helically disposed valve boxes 2 is provided with aeration medium through a seaparate pipe, it is possible to supply aeration medium at the desired pressure to all valve boxes. The blowing of aeration medium from the individual valve boxes may also be regulated, if desired, by means of adjustable valves, which can be disposed in the boxes 2 or on the pipes 3. The fermented products can be removed from the container through a door 9 in the right-hand end plate (as shown in Fig. 1) of the container. Gaseous medium may escape from the container through the opening for feeding waste material and/or through the door 9.

Abstract: 1,098,625. Eddy-current brakes; motor driving arrangements. EPSYLON RESEARCH DEVELOPMENT CO. Ltd. July 2, 1964, [Sept. 24, 1963], No. 37598/63. Heading H2A. [Also in Division G3] A tape transport arrangement for a magnetic tape recorder comprises a torque motor driving each spool, a magnetodynamic brake coupled to each spool and a tension sensing device, associated with each spool, responsive to tension in the portion of tape between that spool and a capstan controlling the braking torque to offset changes in tape tension. As shown, a magnetic tape 13 is withdrawn from a reel 11 and passed over a reading head 17 by a constant speed capstan having a cooperating pinch roller 19, the tape being taken up by a reel 12. The tension on the tape being fed past the head is detected by a loop of tape 26, 27 passing over a guide roller 15 counter-balanced through a lever 23, 24 about a fulcrum 25 by a spring 28. Movement of the lever due to variation in tape tension causes a corresponding movement of a slider of a rheostat 30 to vary the input to an amplifier 31, the output of which varies the excitation of an eddy-current brake so as to tend to maintain the tape tension constant. A similar arrangement is employed for the take-up from the capstan. The reels 11, 12 are driven by motors having a fixed inner part and a rotating outer part, equivalent to the stator, to which a friction brake is applied. The eddy-current brake comprises a ferromagnetic ring having an annular groove, containing an excitation winding, which is concentric with a spindle. The spindle drives a tape reel and carries an aluminium or copper disc which rotates in an air gap between projecting parts of the ring and an end-plate.

Filed: 1957-12-04
Abstract: 876,327. Photo-electric control of processing operations. WALTER, F. Dec. 4, 1957, No. 37833/57. Class 40(3) [Also in Group XVI] In a device for controlling operations on strip material moving through a processing machine the operation is initiated by pulses received from a photo-electric scanner which responds to trigger markers provided on the strip material. When operations are performed at positions which are equally spaced on the strip the scanner pulses synchronize the frequency of an oscillator which supplies an output pulse to trigger the operation and when the positions are not equally spaced a delay circuit replaces the oscillator and the operations are triggered by a delayed scanner pulse. The material is moved through the processing machine by a transport mechanism 3 and pulses produced in the scanner 15 by markers 19 either pass via a delay circuit 16 to a trigger device 14 which operates a processor 12 or (as shown) synchronize the frequency of an oscillator 17 which provides an output pulse to the trigger device 14. Where the operations are equally spaced along the strip the scanner is spaced from the process point 13 an amount equal to distance 21 (marker to point of operation 18) plus any number of complete operational distances 22 and where the operations are unequally spaced a delay time is chosen during which the strip travels the distance between the scanner and processing position minus the distance between the marker and the point of operation on the strip. If an operation requires a stationary strip the trigger mechanism 14 energizes an electromagnet 9 which halts the strip by raising the pressure roller 8. In a second arrangement (Fig. 2, not shown), two scanners are provided, one permanently connected to the delay circuit and the other to the oscillator circuit.

[Class 35.] .In a commutator of the type comprising segments which are embedded in a pressed insulating composition and which have recesses in which a retaining ring is so embedded as to be subjected only to compressive stresses during running, mica or like bars are placed between the outer portions of adjacent pairs of segments and extend radially inwards as far as the embedded retaining ring, the gaps left between the pairs of segments at their inner ends being filled by the insulating composition. Figs. 3 and 4 show in axial and transverse sections a commutator in which the stresses are taken by iron rings e in annular recesses formed in the two faces of the commutator. During the initial assembly in an outer ring, the micas b and segments a are pressed in radially so that the inner ends of the micas are spread on the ring e, as shown at bl, with the result that they centre the ring and are prevented, by their spread ends, from subsequent displacement by centrifugal forces. The insulating composition f, which also forms the hub of the commutator, is pressed into the spaces f<1>, 12 between the ring and the inner and outer faces of the recesses. The inner face of the composition may be seated directly on the shaft without any bushing.

Abstract: 523,327. Force-feed lubricating. TECALEMIT, Ltd. Dec. 30, 1938, No. 37925. Convention date, Jan. 17, 1938. Addition to 513,707. [Class 12 (iii)] The injector of the lubricating apparatus claimed in the parent Specification is modified so that the valve 25 which controls communication between the charging and ejecting chamber and the inlet chamber or the bearing also controls communication between the inlet chamber and the oil line. As shown, a valve 25 having an annular recess 29 is held by a spring 30 in the position shown when the oil pressure in the line 15 is low, so as to connect the inlet chamber 37 below the piston 45 with the charging and ejecting chamber above the piston through the ducts 39, 29, 49, 43, 14 and 16. The duct 52 leading to the bearing is closed. When the oil pressure in the line 15 reaches a predetermined amount the valve 25 moves to open the duct 39 to the oil line 15 and put the ducts 49, 52, in communication with one another. Thereupon the piston 45 moves upwardly and the oil above the piston 45 is ejected to the bearing when the relief valve (not shown) of the lubricating system is actuated to relieve the oil pressure in the line 15 the valve 25 returns to the position shown and the piston 45 under the action of a spring 47 descends to discharge the oil below to the space above the piston. The stroke of the piston 45 is limited by the end 28 of a sleeve 10 screwed into the valve casing 6, adjustment of the sleeve being performed by a wrench 51 after removal of the cap 24. On a reduced portion 53 of the wrench 51 are indicia giving the capacity of the ejector in any adjusted position. A duct 12 passing through the sleeve 10 may be closed by a set screw in the cap 24.
